DESCRIPTION OF THE PREFERRED EMBODIMENTS An air filter pack mounting frame according to a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a diagram showing a mounting frame according to an embodiment of the present invention attached to an air filter pack. In this figure, reference numeral F indicates a rectangular air filter pack, and reference numeral 1 indicates a rectangular air filter pack. Air filter pack F-4
It shows a mounting frame that surrounds the periphery like a picture frame. The air filter pack F is installed on the ceiling of a clean room, etc., with the mounting frame 1 attached in this manner.

The mounting frame 1 is formed by joining four frame members 2, 3, 4, and 5, and these frame members all have the same structure except for the length. It belongs to The frame members 2 and 4 placed above and below the air filter pack F, and the frame members 3 and 5 placed on the sides thereof, have the same length. Each frame material 2,
3, 4, and 5, as shown in FIG. two side pieces 7 extending in parallel and spaced apart from each other by a width;
A receiving piece 8 extends between the two side pieces 7 substantially parallel to the bottom piece 6 so as to form a space therebetween for a purpose to be explained later, and receives one piece of the air filter pack F.
It is equipped with In addition, the frame material is trapezoidal with both base angles of 45 degrees when viewed from the front, just like a single frame material of a picture frame, and both ends thereof have a butt surface for connection that is inclined at an angle of 45 degrees. It is said to be 9. The abutting surface 9 is not limited to the one inclined at 45 degrees as described above, but may be an abutting surface in the range of 45 to 90 degrees.

The space below the receiving piece 8 of the frame member is a space for fitting one piece of an L-shaped connecting fitting 10 used as a connecting member shown in FIG. 2 from the end of the frame member,
Hereinafter, this space will be referred to as the engaging portion 11. A slit 12 is formed in the center of the receiving piece 8 as an opening along its length. The engaging portion 11 includes:
A sealing material 13 (see FIGS. 3 and 4) such as urethane is sealed through this slit 12 by a method to be described later. Further, the mating surfaces of the mounting frame 1 and the air filter pack F are also sealed with a sealing material 13 integrated therewith, and the sealing material 13 also serves as the sealing material 13. Note that the slit 12 is for enclosing the sealing material 13 in the engaging portion 11, so it can be replaced with a simple circular opening or the like.

Both pieces 15 and 16 of the connection fitting 10 have the following:
Spring portions 15a and 16a are formed by cutting out a portion and standing up the portion. Further, the lower part of the receiving piece 8 is connected to the connecting fitting 1 fitted into the engaging part 11.
0 is preferably an inclined surface as shown in the figure so that it is firmly fixed within the space of the engaging portion 11. That is, when joining the frame members 2, 3, 4, and 5 together via the connecting fitting 10, the corner of the joining fitting 10 comes into line contact with the oblique surface of the engaging part 11, and the joining fitting 10 Frame material 2,
3, 4, and 5 are firmly joined.

Next, a method for attaching the above-mentioned attachment frame 1 to the air filter pack F will be explained with reference to FIG. 5 and subsequent figures.

In this installation, first, as shown in FIG. 5, one piece of the joining fitting 10 is fitted into the engaging portions 11 at both ends of the frame material 4 that constitutes the bottom side of the mounting frame 1, and then the mounting frame The other pieces of the connecting fittings 10 are fitted into the engaging portions 11 of the frame members 3 and 5 forming the left and right sides of the frame 1 to assemble the three-sided frame. Next, the bottom frame material 4 is filled with a liquid sealing material 13, as shown in FIG. This filling of the sealing material 13 is performed to completely fill the space within the engaging portion 11 and to a level slightly above the receiving piece 8 . As this sealing material 13, a liquid adhesive such as urethane or silicone resin can be used. This sealing material 13 preferably has a viscosity of about 5.000 to 10.000 cps at a temperature of 20°C.

After this, as shown in FIGS. 6 and 7,
Insert the air filter pack F into the three side frames and seal material 1.
3 is dried and solidified to form a sealing material 13. After the sealing material 13 has completely hardened, as shown in FIG. One piece of the joining metal fitting 10 is fitted into the engaging portion 11, and in this state, the inside of the frame member 2 is filled with the sealing material 13. When the viscosity of the sealing material 13 is low, when filling the sealing material 13, as shown in FIG. Make a stop. The filling amount of this sealing material 13 is about the same as that for the frame material 4 described above. After filling this sealing material 13, the air filter pack F is inserted into the three side frames mentioned above.
As shown in FIG. 8 when turned upside down, the engaging portions 11 of the frame members 3 and 5 are fitted into the other piece of the connection fitting 10 attached to the frame member 2, thereby completing the assembly of the mounting frame 1. . After this,
The sealing material 13 is left in this state to solidify, forming the sealing material 13, and completing the attachment of the mounting frame 1 to the air filter pack F. The sealing material 13 seals the butt portions of the connected frame members from inside the frame members, and also seals the air filter pack F and the frame members 2, 3, 4,
Perform a seal between 5 and 5. In this example, the above 2
You can do two seals at the same time, making your work more efficient. Also,
If a material that is strong after solidification is used as the sealing material 13, the fixing effect of the connecting fitting 10 can be obtained, and the frame materials 2, 3, 4,
5. It can prevent comrades from becoming loose.

Note that the air filter pack F is arranged so that the waveform sides of the filter material are facing up and down, and the sides of the air filter pack F are directly glued to the receiving pieces 8 of the frame members 3 and 5. I'll do what I do.

[0016]

[Effects of the Invention] As explained in detail above, in the air filter pack mounting frame of the present invention, the butt portions of the frame members to be connected are sealed with the sealing material sealed inside the frame members. , the abutting portion can be effectively sealed.
